Sabi's non-contact EEG cap turns silent thought into text
Palo Alto startup Sabi is building a wearable brain-computer interface called the Sabi Cap: a hat lined with in-house, non-contact EEG chips fabricated by TSMC that pick up brain activity and decode internal speech into text on a screen, with no implant or surgery. Sabi says its Brain Foundation Model is trained on roughly 100,000 hours of neural recordings from about 100 volunteers at launch, that the first version targets around 30 words per minute, and that the model can already predict a user's next three to four keystrokes from brain signals; it says neural data is encrypted in transit and during training. Pricing and a shipping date have not been announced, and no peer-reviewed performance data has been published.
If non-contact EEG decoding really reaches usable accuracy, computer input could extend beyond keyboards toward thought-to-prompt, but so far only the company's own claims are public.
